Motorola usb cable

Hello everydoby I have Motorola-branded prolific usb cable. This cable, once inserted in a port, claims to be a 0307 chipset adapter, and Linux kernel doesn't recognize it: not working. Someone told me that Motorola has changed the label in those cables that claim to be 0307, but they are pl2303. Does anyone have one of these cables working? I've tried many ways, including udev, to make it work, but no success. My next step is to recompile the kernel module, but I was wondering if someone has solved it in another way. Bye Dario.
